Context of Lesson:
Overview of lesson, including: where it fits in unit, what are key ideas and what will students be doing.

  • Class time: 1 class period, 47 min
  • Classroom: Biology Lab

  • This activity is a prelude to the study of evolution; students will investigate a series of readings that cumulatively describe a scenario which ventures to explain the origin of life from a primordial sea (soup) to the eventual development of the first cells
  • There are eight short readings (one page or less) each of which will be assigned to one of eight groups chosen by random selection
  • The readings have been handed out prior to the lesson & the students are instructed to read the information prior to class. There are 27 students in the class and there are four copies of each reading, which have been shuffled and distributed to the class so that at least three students have the same reading.
  • The readings come from the University of California, Berkeley education website and the URL is printed on each informational sheet. Students may visit the site for further reading.
  • The students will read the informational sheet; meet with others who have the same reading to construct a summary of their readings and present to the class at large.

Opening Question
  • Cell theory suggests that all living things come from other living things. If that is so then how did the first cell come to be?
  • We will engage in a short discussion which allows students to voice their ideas as to how they think the first cell was formed
  • This should activate some knowledge and stimulate an exchange that highlights a patchwork of unconnected knowledge
  • (I will limit the discussion to 5 minutes)
  • students will then be given an opportunity to reread their homework assignments and
write down the important points of their readings (5 minutes)
